Understanding sepsis.

This article provides information on sepsis, which can be life threatening and is often difficult to identify due to subtle signs and symptoms. It is the body's response to infection resulting in injury to the tissues and organs. Assessment tools can be used to assess risk of sepsis and include considering a source of infection along with a NEWS 2 or qSOFA score. However, it is important to be aware of other subtle changes including cold or clammy skin and changes in the patient's behaviour such as new confusion. Within 1 hour from diagnosis supportive treatments need to be administered, including the most appropriate antibiotic for the source of infection, fluid and oxygen. Blood cultures, bloods including lactate and urine measurement are all needed to support management of the patient.
